I am pleased to have been able to contribute an article on “Cross-border migration and
travel” to IZA World of Labor because the growing complexity of cross-border flows of
people necessitates new approaches to measuring international migration and to designing
effective policy responses

The ongoing relationships between emigrants and
their families, friends, and business contacts in their home countries can
increase outbound and inbound cross-border travel, while cross-border
tourism and business and study trips can trigger migration. New
communication technologies, such as social media and video chat, only
partially substitute for face-to-face meetings. In fact, the greater use of
such technologies boosts demand for in-person meetings. Short- and long-term
cross-border movements are becoming more complex, creating challenges for
measuring immigration and for defining target populations for legislation
and public policy.
